I was search for info on cruise conrtol repair the other day. Kept finding info on resoldering the circuit board. Woke up this morning and desided to pull my tach amplifier apart (tach wasn't working either) and what did I find...a circuit board. took some time to remove the silicone, did some resoldering and ta da...tach working for the first time since I got the car.
Searching takes a lot of time but it's well worth it. Sooo much info at this site...I love it.
Thanks you everyone for putting the info out there.
